Metal tubes are heated with steam. The linear expansion of three
different metals is determined with the aid of a rotating-shaft
pointer. From this the metals' coefficient of linear expansion is
determined (Supplementary problem). The use of a rolling-shaft
pointer is ...
One end of a U-shaped metal rod is immersed in boiling water and
the other in cold water. From the warming of the cold water
qualitative and quantitative statements can be made about the
influence of the rod's composition, length and diameter on the heat
flow through it. Since ...
A polished and a black beaker are heated by radiation. Instead
of solar radiation a bright flame located in front of the two
beakers is used.
Both beakers are filled with air since the heat capacity of water
is very large and it would be too slowly heated.
What kind ...
A measured quantity of water is heated with a heating coil. The
electrical heat output is determined. From the temperature increase
and the heat energy, the specific heat capacity of water is
calculated. This calculation is performed under point 6
of "Evaluation", i.e. ...
Metal pipes made of different materials are heated by passing steam through them. While each pipe is being tested, one end is securely fixed and the other rests on a rotating shaft, the motion of which is indicated with a pointer. The linear expansion of the different metals is ...
By means of the model apparatus for kinetic theory of gases the
motion of gas molecules is simulated and the velocities determined
by registration of the throw distance of the glass balls. This
velocity distribution is compared to the theoretical Maxwell-
Una sustancia gaseosa en condiciones normales se encierra en un
volumen variable y se mide la variación de la presión con el
volumen a diferentes temperaturas. El punto crítico se determina
graficamente con las gráficas (plots) de las
A stream of gas is fed to a throttling point, where the gas
(CO2 or N2) undergoes adiabatic expansion.
The differences in temperature established between the two sides of
the throttle point are measured at various pressures and the
Joule-Thomson coefficients of the gases in ...
Heated specimens are placed in a calorimeter filled with water at low temperature. The heat capacity of the specimen is determined from the rise in the temperature of the water.
The high-pressure steam apparatus makes it possible to measure
steam pressure in a temperature range of 100-250 °C. This allows
for investigations to be performed on real gases and vapours.
Typical equilibrium states between gas and liquid phases can be set
up. For this ...
According of Stefan-Boltzmann's law, the energy emitted by a black body per unit area and unit time is proportional to the power "four" of the absolute temperature of the body. Stefan-Boltzmann's law is also valid for a so-called "grey" body whose surface shows a ...
De acuerdo a la ley de Stefan-Boltzmann, la energía emitida por
un cuerpo negro por unidad de área y unidad de tiempo es
proporcional a la cuarta potencia de la temperatura absoluta del
cuerpo. La ley de Stefan-Boltzmann es también válida para ...
The Stirling engine is submitted to a load by means of an adjustable torquemeter, or by a coupled generator. Rotation frequency and temperature changes of the Stirling engine are observed. Effective mechanical energy and power, as well as effective electrical power, are ...
